Determination of strontium isotope ratios in plant samples by wet ashing digestion
Results in Earth SciencesStrontium isotope provenance analysis has been widely applied across multiple disciplines, including archaeology, food science, and forensics. The establishment of bioavailable ⁸⁷Sr/⁸⁶Sr maps, known as isoscapes, which rely on a substantial number of ...

Angewandte Chemie, EarlyView.Two nanoclusters, Au52(PET)38 and Au70(PET)50, where PET = 2‐phenylethanethiolate, are isolated, which constitute a series of one‐end‐truncated kernel topologies. Both Au52 and Au70 exhibit NIR‐II absorption at 1032 and 1275 nm and nanosecond fluorescence at 1100 and 1360 nm, respectively, with high quantum yields (20.9% for Au52 and 14.8% for Au70 ...

Strontium isotopes as an indicator of human migration – easy questions, difficult answers
Anthropological Review, 2015 Isotope analyses of bones and teeth allow us to study phenomena which occurred in the history of human species and which are difficult to capture by traditional anthropological methods. Measuring oxygen, nitrogen and carbon isotope levels in the skeleton

Source of strontium in archaeological mobility studies—marine diet contribution to the isotopic composition [PDF]
, 2021 The strontium isotope composition of human tissues is widely used in archaeological mobility studies. However, little attention is paid to the relative contributions of terrestrial versus marine sources of strontium in these studies. There is some debate

Decoding Synergistic Pathways in Bimetallic MOFs for Advanced Oxidation Processes
Advanced Materials, EarlyView.This review presents a unified framework linking metal pairing and framework design with electronic structure, redox cycling, oxidant activation, reactive‐species generation, and catalytic performance across photocatalytic and oxidant‐based BMOF‐AOPs. The resulting design principles guide the development of hydrolytically stable and efficient BMOFs for
